Abstract:
A method of forming electrical devices can include electrophotographically printing a particulate material on a device substrate (25). The particulate material is chosen in composition and printed to form at least a portion of the electrical device. An optional intermediate transfer member (22) can also be used to improve reliability and performance of the process. Dry or liquid electrophotographic methods can be effectively used to form electronic devices on a wide variety of substrates not conventionally available in device fabrication.
Abstract:
This disclosure relates to a system and method for fabricating and using a superlattice 1600. A superlattice 1600 can be fabricated by applying alternating material layers 1302 and 1304 on a ridge 902 and then removing some of the alternating layers to expose edges 1504 and 1506. These exposed edges 1504 and 1506 can be of nearly arbitrary length and curvature. These edges 1504 and 1506 can be used to fabricate an array 1900 of nano-scale-width curved wires 1902.

This disclosure relates to chemical sensors 1002. These sensors 1002 may have a dimension of less than 100 nanometers. In addition, these sensors 1002 may comprise field-effect chemical sensors functionalized to sense a chemical.
Abstract:
This disclosure relates to a system (500) and methods (600 and 1600) for creating nanowires (1202). A nanowire (1202) can be created by exposing (614) layers (102 and 104) of material in a superlattice 100 and dissolving and transferring 1610 material from edges (302) of the exposed layers (102) onto a substrate (1802). The nanowire (1202) can also be created by exposing (614) layers of material (102) in a superlattice (100) and depositing material onto edges (302) of the exposed layers (102).
Abstract:
A nanoscopic transistor (20) is made by forming an oxide layer on a semiconductor substrate (S10, S20), applying resist (S30), patterning the resist using imprint lithography to form a pattern aligned along a first direction (S40), applying a first ion-masking material over the pattern (S50), selectively lifting it off to leave a first ion mask to form a gate (S60), forming doped regions by implanting a suitable dopant (S70), applying another layer of resist (S90) and patterning the second resist layer using imprint lithography to form a second pattern aligned along a second direction (S100), applying a second ion-masking material over the second pattern, selectively lifting it off to leave a second ion mask defined by the second pattern (S120), and forming second doped regions in the substrate by implanting a suitable second dopant selectively in accordance with the second ion mask (S130). The method may be used to make an array (10 or 15) of nanoscopic transistors (20).
